I think it may be a false positive. I used some sure predict test this morning and they were negative. I'll try this afternoon and see if they still are. But they would of for sure showed something. That was a one step 10mui test that showed a line.
Now heres a thing. I am using the one step ic 10miu dipsticks and think i am getting false positives on them too they look awfully similar lemme find a pic..
